273-10-24VAC
The Model 273 Single Phase Current Monitor provides essential oversight for industrial applications. It accurately detects over or under current conditions within selectable ranges of 0.5 to 5 amps or 2 to 10 amps, safeguarding connected equipment from potential damage. With automatic reset functionality, operational continuity is maintained without manual intervention, enhancing system uptime. The unit operates reliably across a supply voltage of 24VAC or 120VAC and maintains consistent performance within an operating temperature range of -20° to +131° F. Its robust design includes SPDT output contacts rated for 10A at 240VAC resistive, ensuring dependable switching capabilities. A mechanical relay life of 10 million operations and an electrical life of 100,000 at rated load underscore its durability. This monitor is a practical solution for maintaining system integrity and optimizing operational efficiency.
